Table 5 (pp. 9-10, Croatia, quarterly dummies, region dummies) prints coefficients rounded to 2 decimals with stars only; Table 7 (Zagreb, rounded) duplicates appendix Tables 9-10 and is not extracted. Appendix Tables 9-16 (pp. 19-23) are EViews outputs with coefficient, SE, t and p; White heteroskedasticity-consistent SEs (not stated for Table 12). Regressors: M2 = floor area in m2 (numerical; coefficients in Zagreb and Other region are of order 1e-6/1e-7, suggesting a unit inconsistency in the database - recorded as printed), ROOMS = number of rooms, NEWBUILT = 1 if sold within two years of construction. Location dummies and year/quarter dummies not extracted. Star legend Table 5: *** 1%, ** 5%, * 10%."
